Abstract
In the case of weak birefringence integrated photoelasticity allows for the determination of the distribution of the normal stress in any section of a 3-D specimen. In the case of axial symmetry distribution of the shear stress can also be determined. The question arises how to determine the other stress components. This problem of hybrid mechanics is especially complicated by investigating residual stresses in glass since residual stresses are caused by incompatibility of residual deformations. Due to that, direct application of the compatibility equations is not possible. In this paper formulas are derived for the complete determination of residual stresses in glass in the axisymmetric case and in the case of plane deformation. Examples of complete residual stress analysis are given.
